Blacknight Internet Solutions Ltd. is a 100% Irish owned company which serves the hosting and co-location needs of business, both large and small;[1] it is also the country's largest registrar and the only one that is accredited by ICANN.[2]
Blacknight hosts over 100,000 domains on its servers; which are based with the Data Electronics Group and Interxion, both in Dublin.[3] It is the market leader for the Irish ccTLD, .ie.[4]

Blacknight began offering free one-year registration of .co domains in October, 2012. This free domain offering had been offered for .ie domains since May, but the amount of verification necessary for .ie registration made it a labor-intensive offer.[6]

ICANN

In January, 2010, ICANN authorized the transfer of a bulk transfer of Hosting365 Inc.’s gTLD domains to Blacknight. This action was undertaken due to a compliance issue that resulted in ICANN's de-accreditation of registrar Hosting365 Inc.[7]ICANN explains its decision and the procedures undertaken here
